Title: Magnetic material and its manufacture
Inventor: ONO HIDEO
IPC: H01F1/113
Filed: 1986-12-27
Abstract: PURPOSE:To obtain a magnetic material which is solid at a normal temperature, fluidified by heating, does not lose magnetism when magnetic field is interrupted, and has excellent coercive force, by dispersing ferromagnetic fine grains using a special kind of wax or thermoplastic polymer as a dispersion medium. CONSTITUTION:Ferromagnetic fine grains are dispersed in a dispersion medium, and a kind of solid wax whose melting point is higher or equal to a normal temperature or thermoplastic polymer is used as the dispersion medium. Ferromagnetic oxide fine grains with a diameter of 50-500Angstrom  suspending in water are made to adsorb interfacial active agent. The grains are dispersed in wax melted by heating after dehydration of thermoplastic polymer. In the other case, ferromagnetic fine grains with a diameter of 50-5000Angstrom  are added to wax melted by heating which contains interfacial active agent or to thermoplastic polymer, and are dispersed. Thus a magnetic fluid is obtained. By applying a magnetic field when the dispersion medium is melted, it is possible to give the ferromagnetic grains contained in the fluid changes of position, form, and orientation, etc. These changes can be maintained without vanishing when the magnetic field is cut off, by cooling the dispersion medium under the magnetic field and hardening it.

Title: Controller for hysteresis motor
Inventor: KIKUCHI HIDEHIKO
IPC: H02P27/06
Filed: 1989-11-30
Abstract: PURPOSE:To prevent the rush of current upon throwing a power inverter again by a method wherein the title controller is regulated so that a frequency correcting output for restraining hunting will never become negative upon intercepting the power inverter to detect the frequency of a hysteresis motor under operation. CONSTITUTION:A hysteresis motor 5 is driven by the output of an inverter, consisting of an AC power source 1, a power rectifier 2 and a power inverter 3. In order to detect the frequency (fHM) of the rotation of the motor 5, the output of a power inverter 3 is intercepted instantaneously. A DC current Idc is reduced to zero, a frequency correcting output for restraining hunting (fpcomp) is increased, a frequency control output (fout) is also increased, a power inverter frequency (f1) is increased than the same during the period of putting of the power inverter 3 ON and the frequency (fHM) of the rotation of the motor 5 is reduced. When the motor 5 is put ON, a current is rushed by a phase difference and the DC current Idc is increased, however, the corrected gain of a variable gain proportional device 10a is zero and, therefore, the frequency (fpcomp) will never become negative but becomes zero whereby the frequency control output (fout) will never be decreased so much. According to this method, the frequency (f1) will never become lower than the frequency (fHM) and power-back from the motor 5 may be prevented.

Title: Equipment for measuring amount of wear of trolley line
Inventor: NAKAJIMA KATSUJI
IPC: G01B11/00
Filed: 1990-11-15
Abstract: PURPOSE:To enable wear change in a trolley line sliding surface to be detected accurately by receiving the trolley line from a lower part with a pair of reference rollers at front and rear and holding it from left and right with a holding roller for eliminating displacement of a measurement reference point. CONSTITUTION:A holding bar 4 is gripped and at the same time an operation part 59b of a handle 59 is rocked in a direction of arrow E for separating opposing left and right holding rollers 19 mutually and then reference rollers 17 and 18 are pressed against a trolley line 1 for contacting left and right curved surfaces 29. Then, rocking in the direction of arrow E is canceled and the operation part 59b is rocked in a direction of arrow H, and the left and right rollers 19 are brought closer and the trolley line 1 is held from left and right, thus enabling displacement of a sliding surface to be measured by a non-contact type sensor 2. In this case, a dimension from the sensor 2 to a ear groove 52 of the trolley line 1 becomes constant, thus enabling an accurate measurement to be made. Also, a main body of a measuring equipment 3 can run along the trolley line 1, thus enabling displacement of the sliding surface at a desired position to be measured in sequence.

Title: Reverse power flow preventing method for bilateral power converter
Inventor: INOIE TAKEHITO
IPC: H02J5/00
Filed: 1990-11-14
Abstract: PURPOSE:To prevent occurrence of reverse power flow by detecting effective power of a commercial power supply, and driving solar cells at an optimal operating point when thus detected effective power has a positive value whereas feeding a current command value, obtained by subtracting a value proportional to the effective power corresponding to thus detected effective power from a current command value at the optimal operating point, if thus detected effective power has a negative value. CONSTITUTION:Since effective power of a commercial power supply 1 has a positive value, a function generator 94 outputs 0V in a range where the effective power has a positive value and solar cells 3 are controlled to operate at an optimal operating point by means of a CPU 91 through a control means 9. When the output of the solar cells 3 increases to cause power flow toward the commercial power supply 1 and the effective power decreases to have a negative value, an adder 97 subtracts a value proportional to the reduction of the effective power from a current command value fed from a multiplier 96. The difference is then fed to a bilateral power converting means 5 in order to control the effective power of the commercial power supply 1 to stay in positive state.

Title: Husking rate controller of husker
Inventor: KARAIWA TETSUO
IPC: B02B3/04
Filed: 1994-11-18
Abstract: PURPOSE: To stably control the husking rate of a husker which has a selection rate control function to control the amt. of the rice to be husked in a husking section in accordance with the selection amt. of a selecting section to take out unpolished rice by executing the control by changing a target current value to a fresh current value when a control motor is energized in order to control the amt. of the rice to be husked. CONSTITUTION: The spacing 51 between husking rolls 3 and 4 of the husker is automatically controlled by actuating a husking rate motor 7 in accordance with the load current value of the husking motor detected by a current sensor, by which the change in the husking rate by the wear of the husking rolls 3, 4 is prevented. In such a case, the output value from the current sensor is stored as the target current value of the control at the time of initially setting the spacing 51 by manually controlling the husking rate motor 7. The output value thereafter is compared with the target current value. The husking rate motor 7 is actuated and the spacing 51 is so adjusted that the output value from the current sensor coincides with the target current value when the output value changes to exceed the target current value.  The control is thus so executed that the initially set husking rate is kept constant.
